Photo-Catalytic Degradation of Phenol Using C-TiO2 Nanocomposite

Phenol is among toxic pollutants with a resilient degradability behavior the total removal of which via traditional techniques is impossible. In this research, Carbon-doped TiO2 nano-photocatalyst is produced via sol-gel technique. Various techniques are used to characterize TiO2 nano-photocatalyst such as XRD, FT-IR, EDX, and FE-SEM. Based on the results, the carbon introduced into titania structure has led to response towards visible light. The synthesized catalyst was implemented for photocatalytic removal of phenol in a fluidized bed reactor under UV and visible light. The effects of several significant parameters were investigated such as phenol concentration, pH, time, C/Ti molar ratio and catalyst content. The degradation of Phenol using this nanocomposite is 84 % under UV irradiation during a 180 min period and 70 % under visible irradiation during a 420 min period.
